I think this is where the cache is stored. I see one of the icons on the IRIS home page and the Cache File in the management portal matches exactly with the file name. Still confused as half of the webservers don't need this folder and seem to store it in /opt/webgateway/temp/. Exactly the same version/build.
I think this is a permissions issue as the ones who work out of the box, have apache:root as ownership of that folder, while the ones who don't have root:root.

Hi,

Which version of Cache are you running? 

Had the same issue today in a class, both 2024.1 and 2023.1 versions or IRIS. Very strange, it does not always happen.
